Routing from host to custom defined docker network is missing #520

Describe the bug

I'm using OrbStack 0.15.1, which should already include the feature of making internal docker IP addresses accessible from host. This works correctly when no custom network is define. From what I observed - when starting docker containers from docker compose - a new bridge network is defined and also routing from host mac machine to the created network.

But it seems that this does not happen with custom networks defined in docker-compose. When I define a custom network, no routing rule from mac host machine to the network is defined, so the access to docker container IPs doesn't work.

To Reproduce

The routing does not work with this specific network (I haven't tried other networks yet)

networks:
  default:
    driver: bridge
    name: my.docker.stack
    ipam:
      config:
        - subnet: 10.210.0.0/24

Expected behavior

I should be able to ping containers in the defined network, but it doesn't work

ping 10.210.0.250                                        
PING 10.210.0.250 (10.210.0.250): 56 data bytes
Request timeout for icmp_seq 0
